  1. Wouldn’t a more relevant test for most users be PM reduction per dB of noise? I have never seen this metric used for some reason.

    • Hi Dustin, good observation! We’ve actually done CADR vs noise tests and graphs in the past, but never published them. It’s difficult to show metrics like this because noise levels (in dB) are not linear so it’s difficult to infer a meaning from the number. Having said that a value for CADR per dB could be done, which would give an indication of which purifiers are quieter!
